Example partitioning of a system basis chip with bus interfaces (green), central logic (yellow), and outputs (red) for voltage regulators (LDO), high-side, and low-side switches (HS, LS)
It typically includes a mixture between digital standard functionality like communication bus interfaces and analog or power functionality, denoted as smart power. Therefore, SBCs are based on special smart power technology platforms.
The complexity range for SBC starts with rather simple hardwired devices to configurable state-machine controlled devices (e.g. through a serial peripheral interface).
Various major automotive semiconductor manufacturers offer SBCs.
